摘　　要：针对再生制动失效的问题,城轨车辆主要采用车载制动电阻来进行能量吸收。在对目前国产城轨车辆制动斩波电路中的制动电阻过温保护方案优劣点进行分析的基础上,提出了新的逻辑保护方案。着重介绍了新保护方案的实现方法和优点,并进行了实际地铁线路运行数据的计算验证。结果表明:本文所提出的保护方案具有明显的优越性,应用前景广泛。In view of the regenerative braking failure problem, onboard braking resistors are usually used for metro vehicle regenerated energy absorption. With advantages and shortages analysis of over-temperature protection for existing braking resistor of chopping circuit for domestic metro vehicle, a novel logic protection scheme was proposed. The realization and advantages of the proposed method were introduced in detail, and the practical operation validation was carried out. The results showed that the protection method had obvious advantage with wide application prospects.
